Packages for the release of the Calligra Suite 2.5 Release Candidate are available for Kubuntu 12.04. You can get it from the Kubuntu Beta Backports PPA (which also contains an update to the KDE SC 4.9 beta). They are also in our development release.

Alpha 3 of our development version is available for download and testing. It comes on larger 1GB images, features new applications like Calligra and KDE Telepathy and has a new install version on the ARM images.
